Securing data on an iSCSI SAN-To help secure data transfers between the server and the subsystem, configure security for the login sessions between Initiators and Targets. Using Storage Manager for SANs, you can configure one-way or mutual Challenge Handshake Authentication Protocol (CHAP) authentication between the Initiator and Targets, and you can also configure Internet Protocol security (IPsec) data encryption. NOTE: It is recommended that you use CHAP if the iSCSI traffic uses the public network. Known Issues • Event generated while dismounting a virtual disk-When you dismount a locally mounted virtual disk, the following event may be generated in the system log: Plugplaymanager 12 event: The device 'MSFT 00000000F852A09D SCSI Disk Device' (SCSI\Disk&Ven_MSFT&Prod_00000000F852A09D\1&2afd7 d61&3&000003) disappeared from the system without first being prepared for removal. It is safe to ignore these events for normal Microsoft iSCSI Software Target dismount operations. • Rollback operations on a locally mounted virtual disk-When you mount a virtual disk locally in read/write mode, any rollback operation performed on that virtual disk takes a long time to complete. • Termination of rollback-Disabling a virtual disk during a rollback terminates the rollback operation without a warning. An event is logged documenting that the rollback was ended. • Locally mounted virtual disks are listed in available drives-When you create a new virtual disk, the locally mounted virtual disks are displayed in the list of available volumes to host the new virtual disk. A locally mounted virtual disk does not support storing a virtual disk. If you attempt to select the locally mounted virtual disk as the storage location for the new virtual disk, the following error message is displayed: Appendix 51
